4D Integral with changeable limits

Dear Roottalk,

I need to calculate a non trivial task: 4D integral where the limits of integration are variables of integration. Namely, the integral is:

Integral = int_0^1(int_z^1(int_y^1(int_x^1 F(w,x,y,z) dw) dx) dy) dz

For 3D integration it is possible to perform the calculation, but here I tried to use a class 'IntegralMultiple' with N=4, and I've got a problem with defining limits of each integration. Actually, it is possible to write a recursive function with 1D integration, but it is not efficient.

Is there any effective solution to this problem?

Thanks!
